Metallic Noise Barrier with Transparent Element

Metallic Noise Barrier with Transparent Element

H.S. Engineers Sound Barrier walls are normally used to place a sound barrier between a noise source and a target population.

Sound barriers are an effective means to reduce the noise impact from sound sources affecting sound-sensitive receivers. Common sound sources include roads, highways, railways, retail and big-box developments, Mechanical & HVAC equipment, construction sites, etc. Receivers may include homes or apartments, schools, hospitals, office buildings or even public parks. When noise becomes an issue between such sources and receivers, the use of sound barriers may be an ideal solution.

H.S. Engineers Metallic Noise Barrier with Transparent Element (metallic + polycarbonate or Acrylic)

H.S. Engineers manufactures supplies and installs different types of metallic noise barriers to combat noise pollution coming from linear infrastructures (roads and railways, etc.).

Our Metal noise barriers with transparent element are made of galvanized aluminium or steel panels in between polycarbonate or acrylic sheets, that make up a sound-proof casing inside them along with aesthetic properties and being transparent allows people to view the sceneries of other side. The panels overlap vertically between studs made from steel profiles.

The addition of an absorbent crest increases the acoustic performances. The barriers can be bi-absorbent and can include transparent parts.

ABSORBENT FACE oriented to the focus of noise: The absorbing face is a multi-perforated metallic element. The design of the perforations allow to the sound wave to enter in the panel and being scattered into the absorbent material.SOUND INSULATION: Rockwool achieves a reduction in noise level due to its fibrous and elastic nature, which dissipates the energy of sound waves that penetrate them.REFLECTIVE FACE: The reflective face leaves a space with Rockwool creating an acoustic chamber, so that the sound waves reflect on it into the absorbent material.Supporting structure: consists of MS Steel beams hot dip galvanized and painted with polyester powder paint.The profiles are conveniently sized and arranged with a distance inter-axis depending on structural requirements.The beams are placed in holes already made in the concrete or they have a base plate anchored to the foundation by galvanized steel screws.
